        * h8300/h8300.c (h8300_adjust_insn_length): Adjust the cost of
        shifts by small constant values.
        * h8300/h8300.md: Refine comments.  Remove names from many
        patterns which don't need them.
        (compare insns): Don't underestimate lengths.
        (andqi3 expander): Remove constrains.
        (andhi3): Don't underestimate length.
        (andsi3): Don't underestimate length.  Improve code when upper
        or lower half of destination is being cleared.
        (indirect_jump_h8300, indirect_jump_h8300h): Simplify.
        (shift insns): Remove useless "I" constraint.

        * h8300/h8300.md (bcs type): Remove "bcs" type attribute and
        all references.
        (bcs insns): Delete.  No longer needed.
        (setcc from bitfield): Rewrite to use zero_extract.  Provide
        QImode, HImode and SImode variants.

        * h8300/h8300.c (one_insn_adds_subs_operand): New function.
        (h8300_adjust_insn_length): New function.
        * h8300/h8300.h (ADJUST_INSN_LENGTH): Define.
        * h8300/h8300.md: Remove obsolete comments.
        (move patterns): Tweak constraints.
        (tst patterns): Use "register_operand" for predicate.
        (adds pattern): Use one_insn_adds_subs_operand to get length
        computation correct.
        (subs pattern): Similarly.
        (movstrhi): Remove unused expander.
        (fancy*, pxor, and-not patterns): Remove.  No longer needed.

        * h8300/h8300.c (names_small): Remove "BAD" postfix from
        %r7 byte registers.
        (rtx_equal_function_value_matters): Remove extra declaration.
        (output_simode_bld): New function.
        * h8300/h8300.h (NO_FUNCTION_CSE): Do define this.  Register
        pressure makes cse-int function addresses rarely a win.
        (reg_class): Remove unnecessary register classes LONG_REGS,
        SP_REG, SP_AND_G_REGS.
        (REG_CLASS_NAMES): Corresponding changes.
        (REG_CLASS_CONTENTS): Corresponding changes.
        (REGNO_REG_CLASS): Corresponding changes.
        (REG_CLASS_FROM_LETTER): Corresponding chagnes.
        (output_simode_bld): Declare.
        * h8300/h8300.md: Nuke comments for stuff which has been fixed.
        (all patterns): Remove references to register class "a" (SP_REGS)
        which no longer exists.
        (many patterns): Accept auto-inc auto-dec addresses in more cases.
        (zero_extendqisi2): New pattern for the H8/300.
        (zero_extendhisi2): Only use zero_extendhisi2_h8300 when not optimizing.
        (extendhisi2): Only use extendhisi2_h8300 when not optimizing.
        (extendqisi2): New pattern for the H8/300.
        (bitfield related patterns): Completely rewrite.
        (fancy_bclr, fancy_btst): Deleted.  Redundant with new bitfield
        patterns.
        (addhi3 pattern for h8300): Handle case where we can't make matching
        constraints (works around hard to fix reload problem).
        (stack_pointer_manip): Delete.
        (and not patterns): New combiner patterns.
